“IT’S a puzzle: one dispossessed group after another — blacks, women, Hispanics and gays — has been gradually accepted in the United States, granted equal rights and brought into the mainstream.

At the same time, in economic terms, the United States has gone from being a comparatively egalitarian society to one of the most unequal democracies in the world.

The two shifts are each huge and hugely important: one shows a steady march toward democratic inclusion, the other toward a tolerance of economic stratification that would have been unthinkable a generation ago.

Inequality and inclusion are both as American as apple pie, says Jerome Karabel, a professor of sociology at the University of California, Berkeley, and author of “The Chosen,” about the history of admission to Harvard, Yale and Princeton. “I don’t think any advanced democracy is as obsessed with equality of opportunity or as relatively unconcerned with equality of condition,” he says. “As long as everyone has a chance to compete, we shouldn’t worry about equality. Equality of condition is seen as undesirable, even un-American.”

The long history of racial discrimination represented an embarrassing contradiction — and a serious threat — to our national story of equal opportunity. With Jim Crow laws firmly in place it was hard to seriously argue that everyone had an equal chance. Civil rights leaders like the Rev. Dr. Martin Luther King Jr. were able to use this tradition to draw support to their causes. “Given our culture of equality of opportunity, these kinds of rights-based arguments are almost impossible to refute,” Professor Karabel said. “Even in today’s conservative political climate, opponents of gay rights are losing ground.”

Moreover, inequality has grown partly for reasons that have little or nothing to do with inclusion. Almost all advanced industrial societies — even Sweden — have become more unequal. But the United States has become considerably more unequal. In Europe, the rights of labor have remained more central, while the United States has seen the rise of identity politics.

“There is much less class-based organization in the U.S,” said Professor Karabel. “Race, gender and sexual orientation became the salient cleavages of American political life. And if you look at it — blacks, Hispanics and women have gained somewhat relative to the population as a whole, but labor as a category has lost ground. The groups that mobilized — blacks, Hispanics, women — made gains. But white male workers, who demobilized politically, lost ground.”

Removing the most blatant forms of discrimination, ironically, made it easier to justify keeping whatever rewards you could obtain through the new, supposedly more meritocratic system. “Greater inclusiveness was a precondition for greater economic stratification,” said Professor Karabel. “It strengthened the system, reinvigorated its ideology — it is much easier to defend gains that appear to be earned through merit. In a meritocracy, inequality becomes much more acceptable.”

Inequality has traditionally been acceptable to Americans if accompanied by mobility. But most recent studies of economic mobility indicate that it is getting even harder for people to jump from one economic class to another in the United States, harder to join the elite. While Americans are used to considering equal opportunity and equality of condition as separate issues, they may need to reconsider.”
